    Li, Hjorth & Richard quantify the unlikelihood of seeing a multiply-imaged supernova in A1689, and other clusters.

    Furlanetto et al selected 50-odd clusters in SDSS stripe 82 by richness, in two redshift bins, and then re-imaged in g, r and i at SOAR. Image quality is comparable to median LSST, but depth is only 22-23mag. Interesting sample for algorithm validation, but they are also interested in arc statistics

    In this paper we estimate the number of gravitational arcs detectable in a wide-field survey such as that which will be operated by the Euclid space mission, assuming a LCDM cosmology. http://cgiocoli.wordpress.com/research-interests/moka/
